Find the perimeter of the triangle MNP if MN = 1 1/12 m, NP = 3 1/4 m, MP = 2 5/6 m.

To find the perimeter of a triangle MNP, you need to calculate the sum of all its sides.

Since the sides are already known MN = 1 1/12 m, NP = 3 1/4 m and MP = 2 5/6 m, it remains to sum them up.

MN + NP + MP = 1 1/12 + 3 ¼ + 2 5/6.

First, we sum up the integer parts of the fractional numbers, and separately we sum up the fractional parts, bringing them to a common denominator.

MN + NP + MP = 1 + 1/12 + 3 + ¼ + 2 + 5/6.

MN + NP + MP = 6 + 1/12 + ¼ + 5/6.

MN + NP + MP = 6 + 1/12 + 3/12 + 10/12.

MN + NP + MP = 6 + 14/12.

MN + NP + MP = 6 + 1 1/6.

MN + NP + MP = 7 1/6.

Thus, the perimeter of the MNP triangle was 7 1/6 m.

Answer: MNP perimeter = 7 1/6 m.
